Node.js Meets Docker
summary
PayPal migrates Node.js apps to containers, rebuilding deployment with Docker images, dockerfiles and Alpine base image to get immutable, layer-cached artifacts. Advice includes splitting COPY to avoid npm install cache busting, using volumes for persisted data, writing logs to stdout routed via Fluentd, health checks and graceful shutdown via signals, and composing services with docker-compose or Kubernetes for orchestration, canary deploys and autoscaling. Outcome: multiple language stacks (five or six) share layers and deployments become declarative and more reliable.
